Title: An improved method of and machine for coating running webs
IPC: D06B3/18
Filed: 1960-10-05
Abstract: 910,341. Coating webs; paper. MEYER, H-E., [trading as MASCHINENFABRIK MAX KROENERT KOMM.- GES.]. Oct. 5, 1960 [Oct. 9, 1959], No. 34089/60. Classes 96 and 140. A method of coating a paper or textile web 1 with a fusible material, e.g. a natural or synthetic wax, paraffin wax or low molecular weight polythene, comprises applying the material in molten state, e.g. in a bath 5, and passing the coated web, while the coating is still plastic, between a pressure roller 8 and a polished, cooled roller 9, maintained at a temperature below 15‹ C., to produce a glossy coating on the web. If the web is coated on both sides, as shown, a second cooled roller 14 is provided, contacting the roller 9, or the roller 14 may have a separate pressure roller, the web being passed through the nip so formed instead of between rollers 9, 14. Radiant heat or a heated roller at location W may be provided to maintain the coating molten prior to engaging the roller 14. The rollers 9, 14 receive a flowing cooling medium and the roller 8, which may be rubber-covered, is urged by springs against the roller 9. The coating weight should not exceed 25 gms./square metre.

Title: Machine for loading piles of newspapers on a pallet
IPC: B65B35/50
Filed: 1964-08-20
Abstract: 1,023,760. Stacking newspapers on pallets. BONNIERFORETAGEN A.B. Aug. 20, 1964 [Aug. 23, 1963], No. 34114/64. Heading B8C. A row of piles of newspapers is pushed on to trap doors 30, 31 (Fig. 5, not shown) on a stacker 14 (see also Fig. 1) which is lowered to a position where the row is dropped on to a pallet 23 which is subsequently moved one step forwardly to receive the next row. In the form shown, each pile is delivered from tines 26 on the descending run of an elevator 25 which overtakes the stacker during its descent to transfer the pile of tines 27a (Fig. 2, not shown) on the stacker; a plate 29 then pushes the pile on to trap doors 30, 31. When the last pile of a row has been pushed on to the doors 30, 31, the first pile strikes against a switch 48 (Fig. 5, not shown), which actuates a solenoid valve to admit air to a cylinder 33 so that a yoke 49 attached to the doors 30, 31 is depressed and the doors swing down. Downward movement of the doors actuates a switch to start the upward movement of the stacker. In the upper position switches are tripped to raise the doors 30, 31 and start the forward movement of the pallet conveyer to receive the next row of piles. Fully loaded pallets 24 (Fig. 1) are removed on a conveyer belt 18 and empty pallets 22 fed beneath the stacker. The distance between the doors 30, 31 is adjustable so that different widths of newspapers may be stacked.

Title: Pneumatic Jacks
IPC: E05F15/50
Filed: 1968-07-18
Abstract: 1,193,229. Pneumatic jacks. KLAUS ESSER K.G. 18 July, 1968 [18 July, 1967], No. 34353/68. Heading B8J. In a double-acting pneumatic jack for opening and closing and for varying the degree of opening of cover members, such as windows or light domes, chamber 4 is divided by a wall 6 to form a chamber 12 containing an auxiliary piston 7 and a pair of spring-loaded tilting look-plates 14, 15 which, in the rest position shown, hold pistontod 1 against movement in either direction. The plates 14, 15 are engaged by one end of a forked arm 17, the other end of which is secured to a fixed point 16. Cylinder 3 is pivotally secured to the point 16 by a lever arm 18 pivoted to the cylinder 3, which arrangement permits slight axial movement of the cylinder 3 with respect to the arm 17. In order to extend the rod 1 compressed air is supplied through conduit 19. The rod 1 being locked, pressure in chamber 5 moves the cylinder 3 downwards until the piston 7 is engaged by the end of the cylinder 3 and moved with the cylinder 3 to disengage the lock plate 14, Fig. 2 (not shown). The rod 1 is then free to move upwards to a desired position. At this position the air pressure in conduit 19 is reduced and the chamber 5 is discharged via high-speed vent valve 20. The weight of the rod 1 then causes it slightly to reverse its movement thereby angling the plate 15 to lock the rod 1. To retract the rod 1 from the rest position compressed air is supplied through conduit 8 forcing the piston 7 down to unlock plate 14 and uncover branch conduit 11. Build-up of pressure in the chamber 4 lifts the cylinder 3 to unlock the plate 15, Fig. 3 (not shown), whereupon the rod 1 is retracted by the continuing supply of compressed air to the chamber 4. At the desired position the air pressure in the conduit 8 is reduced whereupon high-speed vent valve 21 opens so that the cylinder 3 can move downwardly removing from the plate 15 the support of the wall 6 and the plate 15 again locks the rod 1. Several jacks may be interconnected for synchronous movement (not shown).

Abstract: 176,501. Hudson, J. G. Dec. 7, 1920. Spray carburettors.-The whole of the air, preferably heated, is admitted past a suction-actuated pivoted valve A upon which is freely mounted a bell-crank lever E, one arm of which engages a fuel valve B, the other arm carrying a roller H which bears against a finger C adjustable from the dash-board. A dash-pot G prevents fluttering of the fuel valve and leakage of air past its spindle. For starting, the finger C is moved into the position D, X, which causes the fuel valve to open fully for a small opening of the air valve, at which small opening air is admitted at high velocity both above and below a curved perforated plate J. The running position of the finger C is indicated at Y, and the coasting position, for air with no fuel, at Z. The mixing chamber K is jacketed at M by water or exhaust gases and contains baffles in the form of wires W. The needle valve may be tapered and formed with four flats. The cover N is secured by a togglearrangement comprising an arm Q pivoted at R and engaging at its upper end a bridle wire O pivoted to projections at P on the body.

Abstract: A linear thermosetting polymer contains units derived from a bisphenol containing an unsaturated alicyclic group, and carbonate linkages, and optionally also residues of 1,4-butenedio or 4-cyclohexene-1,2-dimethanol or a hydroxy terminated polyester chain, derived from a diol and a dicarboxylic acid, having a molecular weight of 800-5000 and in which the diol or the diacid is olefinically unsaturated, or residues of maleic, fumaric, itaconic, citraconic or ethylidenemalonic acids.  The preparation of suitable bisphenols is described in Specifications 1,024,012, 1,024,013 and 1,024,014.  They are condensation products from 2 moles of a phenol and 1 mole of an unsaturated alicyclic, aldehyde or ketone. Suitable components for the polyester chain are the above-named unsaturated diols and dicarboxylic acids.  The polyesters are prepared by condensing the bisphenol with phosgene and optionally a bischloroformate of 1,4 - butendiol or 4 - cyclohexene - 1,2 - dimethanol or the unsaturated polyester, or with the unsaturated dicarboxylic acid chloride and phosgene and/or a diol bischloroformate.  Coat ing compositions are prepared by dissolving the polyesters of the invention in a volatile solvent, e.g. methylene chloride, and adding a catalyst for the thermosetting reaction. 10-30 weight per cent of the polyester may be replaced by an unsaturated alkyd resin, e.g. one from a diol and maleic, fumaric, itaconic, citraconic or ethylidenemalonic acid, or from linseed oil, dicyclopentadiene and e.g. diallyl phthalate or maleate or divinyl benzene.  In examples, polyesters are prepared from phosgene and diphenylol (3 - cyclohexen - 1 - yl) methane, diphenylol-(6 - methyl - 3 - cyclohexen - 1 - yl) methane, diphenylol - (3 - methyl - 5 - norbornen - 2 - yl) methane and 6,6 - diphenylol - hexahydro-4,7-methano-indane, and from phosgene and the latter two bisphenols with fumaryl, itaconyl, or ethylidenemalonyl chloride, or cyclohexene - 4,5 - bischloroformate or the bischloroformate of a hexane diol/itaconic acid or butane diol/sebacic acid or a cyclohexane dimethanol/maleic acid polyester.
